H-2 evolution from aqueous potassium sulfite solutions under visible light irradiation over a novel sulfide photocatalyst NaInS2 with a layered structure
NaInS2 which consisted of anion layers of InS2- with a 2.3 eV band gap showed the photocatalytic activity for H-2 evolution from an aqueous K2SO3 solution under visible light irradiation (lambda > 420 nm).
